E2D0020-39-93 ¡ Semiconductor ¡ Semiconductor MSM9810 8-channel Mixing OKI ADPCM Type Voice Synthesis LSI This version: Sep. 1999 MSM9810 Previous version: May 1997 N ew GENERAL DESCRIPTION The MSM9810 is an 8-channel mixing voice synthesis IC, to which up to 128 Mbits of ROM and/ or EPROM storing voice data can directly be connected externally. The device is straight 8-bit PCM playback, non-linear 8-bit PCM playback, 4-bit ADPCM playback, and 4-bit ADPCM2 playback selectable and provides 2-channel stereo output and volume control. The MSM9810 contains a 14-bit D/A converter and LPF. The MSM9810 can easily configure a system by connecting voice data storage memory, power amplifier, and CPU externally.
